Abstract

Nanotechnology has today turned out to be a buzzword. Its expansion in a different field is phenomenal. But for some reason, it has been holding the rate of development. To count reason behind being its failure despite such promising properties is its high-cost production and potential harm to nature. Beside the less significant amount of production, there is a need for the eco-friendly, less toxic and cleaner method of its production. It could not have been more favorable, in case if it could lead to an increase in production at the same time in its efficiency too. Algae mediated biosynthesis of the nanoparticle is one of the probable solutions of the above-mentioned drawbacks. This review article focuses on the synthesis of nanoparticles with help of algae and their potential benefits over conventional based methods. It takes into consideration, the formation of nanoparticle through cyanobacteria, microalgae, and macroalgae.
